Commit 2708ddfb06a36d8568e2aa130bf1f7d551fcd309 caused a few regressions.
We need to check/validate state after calling bind_arrays() because
it might set the _NEW_ARRAYS flag if the varying VP inputs change.
The symptom of this problem was some attribute arrays being ignored
(or interpreted as constant-valued) in glDrawRangeElements or
glMultiDrawElements.
A follow-on patch will add some additional asserts to try to catch
this kind of thing in the future.

...rather than checking/validating before all the calls to
_mesa_valid_to_render() and valid_to_render().
The next patch will actually fix some bugs...

These changes were originally submitted by Karl Schultz for Mesa 7.7-rc2
but weren't applied.

builds.
The driver (or preferably the hardware) should handle out of bounds
indices.
If there are problems then it's better to detect those in the debug
builds.

Changes in v4;
- Implemented Brian Paul's style suggestions
Changes in v3:
- Use positive caps instead of negative ones
Changes in v2:
- Updated formatting
The state tracker will use the TGSI convention properties if the hardware
exposes the appropriate capability, and otherwise adjust WPOS itself.
This will also fix some drivers that were previously broken due to their
incorrect, inadvertent, use of conventions other than upper_left+half_integer.
|
|
Exposing it was incorrect, as the GLSL part of the extension is
missing.
We still keep the ARB_fragment_coord_conventions field, so that the
ARBfp parser can know whether to accept or reject the keywords.
|
|
Note that when detaching the PBO from the region and making a new BO
for the region, we don't make it tiled even if the region originally
was.
Fixes piglit pbo-teximage-tiling.

same variable used for 2 different temp registers
fixes e.g. glsl/bump

So if we don't actually emit an atom to the hw because we don't
need it in the current state (e.g. lighting related atoms when
lighting is off) then don't mark it as clean, because when
lighting gets switched on we won't emit it at all.
This fixes funky gears colors.

mesa core does it now. If only it did so for other entrypoints.

This reduces the driver size by over 1%.

Bug #25921 -- clutter PBO usage gave unreliable results.
|
|
|
|
As with swrast, this fixes the default pixel center behavior which was
broken, and implements the previous behavior for integer. Fixes
piglit fp-arb-fragment-coord-conventions-none. The extension won't be
exposed until we get the GLSL part implemented.
The DRI1 origin_x/y parts are dropped since they're no longer relevant.
|
|
This brings swrast's support up to the state of gallium, and fixes the
default center behavior of fragment.position.xy in piglit
fp-arb-fragment-coord-conventions-none.
The extension is not enabled currently because the GLSL part of the
extension isn't supported, so piglit
glsl-arb-fragment-coord-conventions-define fails as would any serious
test of the GLSL part.
|
|
Merging was easier than cherry picking in this instance.
|
|
If GL_EXT_framebuffer_blit was not supported _mesa_DeleteFramebuffersEXT
would raise an error when deleting the currently bound framebuffer. This
because it tried to bind the default DRAW- and READ_FRAMEBUFFER separately.
This patch binds the default FRAMEBUFFER instead in that case.
Encountered in the fbo/fbo-copyteximage piglit test on R600.
Patch cleaned up a bit by Brian Paul.
|
|
Now that LOCK_HARDWARE is gone, we don't have a convenient place to
update the renderbuffers everywhere we need them. So grab new buffers
when we invalidate the old ones until we optimize things further.
|
|
If we determine that the 'end' parameter to glDrawElements() is out of
bounds, clamp it to the max legal index value.
|
|
Some apps are sloppy with their start/end values. Clamp them to
max possible values to prevent problems later.
|
|
Eric added some new code to check if offset < obj_size before computing
_MaxElement but my original code was still present afterward and it
clobbered the _MaxElement value.
Not sure if this came from a bad merge or what.
